That would be weird. "Normally" in a reg like that there are two inlets and 1 outlet, and a gauge port which is also connected to the inlets. Outlet goes back to the tank, inlet(s) go to the fuel rail(s).

^ This.

OP: You have a megasquirt, why the hell are you fooling around with a FPR? Just go buy proper injectors already. There is a set of Denso RX8 425cc injectors in the classifieds right now for $125, that'll get you started.

its not made by ebay douche bag. my stock fpr is fucked up.and the hoses need be replaced, alot of things in my engine bay are over 20 years old and why not get one from Majesty they have great reviews and are better and cheaper than getting an oem one from mazda for 170$

How did you **** up your stock fpr? And why didnt you just post a wtb for a stock one? Someone would have give you one for $10.

The stock fpr is 200k miles old, its only sending 20psi, and twitching. The fuel lines are dried out and wearing away, the kit comes with new steel braided line and an fittings.
Does the stock one rise in pressure like a rising rate fpr?

Even if so, it won't rise with boost because well... was your car turbo from factory?

Car is not turbo i am naturally aspirated,
Built motor headers ms pnp, and i have a vaccum gauge, do i need to keep that tapped in on my vaccum line constantly? That does not sound safe having fuel regulator attached to a vaccum line that goes to a gauge in my cab
